Sunrise and Sunset device via shellsensor plugin

---

@sweebee Sorry i can’t get the 24 hour format to work. I also don’t know why the pimatic-sunset-plugin can’t be used for the GUI interface? https://github.com/pimatic/pimatic/issues/479

Hey folks,
the script doesnt work anymore.

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<yahoo:error xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" xml:lang="en-US" yahoo:uri="http://yahoo.com">

yes, this is not working since yahoo changed api and other codework.
there’s no “global” solution available yet.

our devs are still on checking v0.9.
this issue here is on the improvement list but guess this will be arranged after v0.9 is out.

Unfortunately Yahoo disabled the API access, requiring OAuth authorization now.

There is another link returning an XML file with the data. Maybe someone could adapt the awk command (I’m not that experienced in that).

This is the URI: https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid=[ID]
(courtesy of https://forum.rainmeter.net/viewtopic.php?f=13&t=23010)

doesn’t make any sense to set on yahoo anymore if you ask me.
even if there are some loopholes in their api, they will surely fix them soon.

I guess you’re right. Well, I made the switch to Sunwait (https://www.risacher.org/sunwait) which makes it independent from Yahoo.

sunrise=$(curl -s https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid=[ID]| grep astronomy | awk -F" ‘{print $2 “\n” $48;}’ |{ date -f - +%R; })
sunset=$(curl -s https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid=[ID]| grep astronomy | awk -F" ‘{print $2 “\n” $50;}’ |{ date -f - +%R; })

This is wirking but not very well

Just to bridging the gaps until the extended version of pimatic-sunrise is ready, I have implemented a simple command line tool based on suncalc. Actually the tool is a fork from another project. Thus, my code is not availble as a npmjs package, but it can be installed via the npm tool if you have git installed. See README

suncalc-cli -v sunset -l 52.5072111,13.1449592,10 -d tomorrow

Hi, a new version of pimatic-sunrise is available which contains a SunriseDevice. See README for details.

Great work. It works fine.
How often does it refresh? Once a day?

@Harry-van-der-Wolf every night. see: https://github.com/pimatic/pimatic-sunrise/commit/35b26092b2885357477a43e675ba8887f2634c91#diff-3129b173d9e2711c7b26c24515b25acdR106

thx @mwittig for that very very nice extension of the sunrise plugin!
it’s working fine for me!

@leader21 Welcome. It’s great, it is working fine for you! As we already discussed on chat you may experience a derivation of suntimes by a few minutes (3 minutes in my case) when compared to data from weather sites. This is due to the following reasons:

• The weather site may use data from another location than the one you have set
• Suncalc is less accurate than it could be (rounding errors may occur) - see also https://github.com/mourner/suncalc/issues/57

yes i experienced appr. 5 minutes differences. but that does not matter anyways.

allright guys - go ahead and use this new device for your needs

That’s the way I like, perfekt work for me!
A few minutes difference don’t matter for me, more difference in light is from the weather itself

OK why parse an xml and make your system dependend from another source?

Try this. Create an php make it executable and then you are on your own system without external sources.

You can get sunset and sunrise via sun.php riseset or the position of sun with sun.php pos.

thx for your workaround!

as part of the recently upgraded sunrise plugin, the new suntime device is working very well, even without any external source parsing.

OK, but how does it work? Are this inside of sunrise plugin?

it’s using suncalc.
have a look at the code from @mwittig
https://github.com/pimatic/pimatic-sunrise/commit/35b26092b2885357477a43e675ba8887f2634c91

Yes, i know this plugin. But i dont understand how to create a device to see this in my GUI.
I don’t find any documentations about this.
We are talking about this plugin???
